Abstract

A linearized finite-difference scheme has been used to investigate the mixed convection boundary-layer flow about a liquid sphere subjected to an air stream. For Prandtl number = 0.7, velocity and temperature profiles are obtained for a wide range of the other controlling parameters: Reynolds number, interior-to-exterior (liquid-to-air) viscosity ratio and Grashof number. Both aiding and opposing natural convections are considered in this study. The effect of the controlling parameters on engineering quantities such as the shear stress and the Nusselt number is also presented.
